Exact match searches are "regular searches" (one of the 4). You just need to put the '=' inside the quotes.

EDIT: perhaps I misunderstood. Are you looking for word-level matching, as in "sister" matching "my sister jane" but not "the sisterhood of jane"? If so then as you say, the built-in search types won't help you beyond regex and template searching.
